Give one word answer (i) an insoluble salt mat fall out of a solution-
Answers
Explanation:
In this class practical, students react two soluble metal salts to produce one soluble salt and one insoluble salt. Lead nitrate solution and sodium chloride solution react to produce solid lead chloride, leaving sodium nitrate in solution. Students can recover the lead chloride by filtration or centrifuge
Using the procedure below, the experiment should take no more than 30 minutes to the point at which the solution produced has been filtered. If reagent solutions are provided in ready-measured quantities in small labelled bottles, the experimental work can start immediately.
Most classes should be able to perform this experiment as a class experiment, but if there are real doubts about safe behaviour or adequate manipulative skills while solutions are being heated, or hot solutions being poured into the filter paper, then student-aided demonstrations of these may be more sensible.
